Status: offline 		Hello all I am running a regulated 1950 mah 6 volt pack. I picked it up and the regulator for a lot less than a Duralite setup. I think 6.0 volt is the way to go that way if a cell fails you will not lose your gyro or reciever functions. Alot of other members use the Duralite setup but I just did not want to spend the extra $$$ I got my setup, 2 1950 nimh's and a regulator for less than a $100.00 I get great flight times and can have 1 pack charging if I want continuos flying. I am not saying don't go Duralite but if you are just starting you can save some $$ in this area and still have a very good setup. I bought my setup from NOBS batterys, they advertise here on RCU. Lastly NOBS sells the second pack at I think a %25 discount when you buy two.

Status: offline 		Yes the receiver will work on 6V. I am not sure what gyro you are using but the popular Futaba 401/9254 combo will not last long using 6 volts. 6volts will also increase you servo tourque and decrease transit time but some servos can not handle 6V. I think this is more of a problem with digital servos.

Hi,
I think (but not totally sure) that Futuba can handle 6v, while JR need to run at 4.8v. That is from a far and distant memory so if anyone has more up to date info, please correct me.

If I understand BH correctly is he saying it slowing the collective/throttle response time?


No, you want to set the throttle end points around 70-80. The servo will get to the end point quicker that the collective servo which you set to 110-120 end points. This way the throttle is always ahead of the pitch demand and so keeps the RPM from slowing down as much. What I think BH is saying is that he was unable to run these settings with the PP system, so he elected to go with the single pushrod system. I am using PP on my Titan and have been able to set mine up like this and the throttle does stay ahead of the pitch servo.

I have not done anything to prevent fuel getting into my tail servo. If anyone has a method of sealing it please post it.


Cheers

Status: offline 		The higher end points are a little slower but as BF said it allows the throttle to stay ahead of the collective. You could also use a faster servo.

The main reason I did away with the push pull was to put the rudder servo in the nose.

Any modern recievers will run on 6v as will the gyros. The tail servos have a VERY narrow dead band. The higher you push the voltage the narrower the dead band so they can chatter themselves to death at higher voltages, though they are known to work ok at 6v regulated, I just prefer to regulate to 5.1 or 5.3, I'm not a good enough pilot to need that extra .7v and my servos last longer.

Thanks for the info BH. I suspected things would have change since I heard that. I never really left the hobbie but I was ill for a few years and didn't keep as current as I would have liked to.

Status: offline 		Yup, you use a 6v battery and connect it to a 5.1v regulator. The good bit is that if you loose a cell in you battery the voltage drops to 4.8v. Your electronics will still run at 4.8v and so you don't make a big hole in the ground with your pride and joy.
Also, some regulators have a fail to on switch so again if you are unlucky and have a switch failure you still land ok, and when the heli won't switch off you realise you have a problem.
The regulator has a regulated (5.1v) and unregulated (6v) lead. If you put a voltspy or simular on the 6v lea(set to monitor 6v) then you can immediatly spot a dead cell as the red LEDs come on, or you just ran down your battery if you have flown a lot.
I don't have one on my Titan but I'm gonna fit one.

This was a big step mentally... I'm about to get hooked on heli's.

That's a pretty picture!!

I think everyone has "Shrek" paddles but me.

LOL, I don't either.

Barracuda, very crisp picture. I am uber exited to get this heli flying, but not much build time. I am at the point where you assemble the tail.

I will purchase a 5.1 regulator, like helimedic said...sounds easy enough.
